Having had several websites of my own I can attest to the fact, they are expensive to maintain and about the only way to keep one is to depend on advertisers.
Do not condemn the advertisers, they help keep the doors open.
My sites closed because I could not find advertisers. We should thank Bro.-S- for his ability to find advertisers, that in itself is a hard job.
I doubt if Bro -S- wants to discuss the costs of operating the forum. We are fortunate he has found ways to do it and we need to trust his judgment. We all need to support his efforts and decisions to keep the forum open.
Sit back, relax and stop worrying so much.
